I noticed that the following happen even with obove if the package which requires libsvtav1 is installed. At the first upgrade, Uninstall libsvt1v1 1.8.0-1 Install libsvtav1dec0 1.8.0-2 Install libsvtav1enc1 1.8.0-2 that is as expected except for libsvtav1dec0 is not latest. However, at the next upgrade (just run setup again), Uninstall libsvtav1dec0 1.8.0-2 Install libsvtav1 1.8.0-1 Install libsvtav1dec0 2.0.0-1 happens. This causes conflict: $ cygcheck -f /usr/bin/cygSvtAv1Dec-0.dll libsvtav1-1.8.0-1 libsvtav1dec0-2.0.0-1 Im not sure why this happens. Contrary to your idea, libsvtav1enc1_OBSOLETES="libsvtav1" libsvtav1enc1_REQUIRES="libsvtav1dec0" the followings happen as expected. Uninstall libsvtav1 1.8.0-1 Install libsvtav1dec0 2.0.0-1 Install libsvtav1enc1 1.8.0-2 Of cource, libsvtav1dec0_OBSOLETES=libsvtav1 should be removed in this case.
